I found out that the "apmsleep -s 00:01" (with little 's') does not wake up
on either network or usb. However, "apmsleep -S 00:01" does almost what I
want. The apmsleep with big S does not seem to shut down hdd, but I can do
that using hdparm.
I have problem since the "apmsleep" with big S does not only wake up
(correctly) on USB, but also on broadcast network packets! Disabling "wake
up on network" in BIOS won't help, nor ethtool
# ethtool -s eth0 wol g
Cannot get current wake-on-lan settings: Operation not supported
not setting wol
# dmesg | grep eth
eth0: Lite-On 82c168 PNIC rev 32 at ca812000, 00:A0:CC:62:2B:2A, IRQ 10.
